Answer:
56 5/8
Step-by-step explanation:
453/8
Answer:
3
Step-by-step explanation:
3(1)² - 5(1) + 1
3x3 = 9
9-5+1
9-6 = 3
(-2, -9)
Simply plug -2 into the equation.
This can be written as 3(n+12)=45, where n is the unknown number
3(n+12)=45 <- Starting Equation
3n+36=45 <- Distributive Property
3n=9 <- Cancel 36 on both sides
n=3 <- Divide both sides by 3
So n=3
Hope this helped!
